Rep. Jason Chaffetz (R-Utah) is expected to announce Thursday that he is resigning before the end of this congressional term, according to three sources familiar with his plans.

Chaffetz did not respond to a request for comment Wednesday evening or Thursday morning. Multiple sources say he will leave Congress on June 30.

Chaffetz, 50, is chairman of the House Oversight and Government Reform Committee, the top investigative body in the chamber. He recently subpoenaed James Comey's memos, and invited the fired FBI director to testify next week before his panel.

Chaffetz told POLITICO last month he had begun exploring employment outside Congress. Several sources in the Capitol say Chaffetz has told his colleagues he will appear on Fox News.

I don't even know who that is, but I've seen his name around here, and Reddit is, again, abuzz. Good reporting on my part or not?
